All geek questions in one place

Is there a list of errors that will appear as "segfaults" if they are really not related to memory access?

In this question, I found out that trying to run privileged commands when not in ring 0 can lead to what looks like segfaultin a user process, and I have two subsequent questions.

  • Does this apply to all privileged instructions?
  • What other types of errors can fake segfault cause, but are not related to trying to read memory?
